CABINET.

Application filed April 16, 1925. Serial No. 23,600.

The present invention relates to improvements in shelf cabinets and has particular reference to a cabinet provided with a plurality of shelves that may be irregularly iiiterposed between stacks ofarticles so as to allow the entire space within the cabinet to be used for storing the articles, each shelf resting immediately on the stack of articles below it. In order to render the different stacks accessible without disturbing the superimposed stacks, it is necessarythat pro vision be made allowing each individual shelf to be raised so as to lift the same from the stack it is resting on. It is proposed in the'present invention to provide slidable side panels for this purpose in combination with means allowing each individual shelf to be selectively secured to the side panels and in combination with means for allowing both side panels to be raised simultaneously.

A similar device has been described in my co-pending application Serial No. 699,922, which has become Patent Number 1.556,?11, and the'present device has various novel features incorporated therein which I desire to claim in the present application.

The preferred form of my invention is illustrated in the accompanying drawing. in

which'- Figure 1 shows a front view of my cabinet.

Figure -5 a vertical section taken at right anglesthereto andsubstantially along line VV of Figure 1, and c a '1 Figure 6 a detail view, of amechanism in corporated in each shelf for selectively securing the same to and releasing the same from the panels disposed at opposite sides thereof. I r I While I have shown only the preferred form of the invention, it should be understood that various changes or modifications may be made Within the scope of the claim hereto attached without departing from the spirit of the invention.

Inits preferred form my cabinet 1 comprises a single compartment which may be open in front and is preferably rectangular in horizontal section. It preferably consists in its general structure of four posts, two arranged in the four corners of a rectangle and connected by a rear wall 3 and'side walls 4. A raised bottom 6 furnishesa floor for the compartments on which the articles to be stored may be placed. 4

Along the side walls of the cabinet and held in spaced relation thereto by means of frames? I provide the sliding panels, 8 secured to the inside of the frames 7 which latter are provided with downwardly projecting bolts 9 extending through suitable apertures in the floor 6 and its supporting elements and interconnected below the floor 6 by means of' a transverse bar 11. The up- 7 0 per ends ,of the sliding panels 8 extend into slots 12 in the top 13 of the cabinet and are adapted to slide into caps 14 disposed on top of the cabinet when the side. panels are raised bymeans of the device to be described 7 5 hereinafter. The caps 14 not only serve the purpose of accommodating the upper ends of the sliding panels but may also be used as end supports for a series of hooks placed on top of the cabinet. For operating the side panels I use the foot board 16 pivoted in brackets 17 extending internally from the front posts of the cabinet near the floor on which it rests. This foot board has a ver-- tical board 18 hinged to the rear endthereof as shown at 19 with 'chains21 connecting distant portions of the two boards so as to preventthe angle between the same from exceedinga certain degree. The upperend of the vertical board 18 is connected by means of-cords 22 to the cross bar'11, the cords being first guided over pulleys 23 disposed abovethe bar, so that when the foot board 16 ispressed upon the bar ll and with it the structure supporting the two sliding panels are raised. A catch 24 is hinged to the front edge of the bottom board 6- or any other transverse member suitably arranged between the two front posts, as shown at 26, and is adapted for engagement withthe upper edge of the board 18' for locking the same against return motion when the structure supporting the panels is raised. A bolt 27 arranged slidably relative to the board 18 extends into operativeproximity to the we catch 24 and may be advanced for releasing the board from the catch by means of a lever 2 8 pivoted upon the hinge 1 9 and engage the'bolt as shown at 29. A springBl a bearing on the other side of the lever 28 11 normally prevents the sliding bolt 27 from becoming active,

links 46.

The space between the sliding side panels may be used for storage of articles and a plurality of shelves 32 are provided to be irregularly interposed between various stacks of articles so as to immediately rest upon the same. Only two shelves are shown in the drawings but it should be understood that any number of shelves may be used. A detail view of one of the shelves is shown in Figure 6, a cover panel being removed to disclose the inside of the same. The shelf is of substantially the same form as the com partment and when placed into the same fills the horizontal extension thereof; Each shelf presents a hollow interior, as shown at 33, and may be made of a frame 3% representing two side members 36 and a rear member 37 with two thinpane o8 covering the space enclosed by the frame. Two bolts 39 are slidably mounted in each side member 36 of the shelf and are urged outwardly by,

means of springs 41 adapted to project the bolts into registering perforations 42 provided in the sliding side panels. A lever i3 is pivoted near the center of the shelf as shown at 44 and has two points disposed on opposite sides of the pivot secured to two diametrically opposed bolts 39 by means of The lever normally allows both bolts to project outwardly due to the action of their respective springs, but permits the two bolts to be retracted by manipulation of the operating end 47 of the lever projecting outside of the shelf. The retracting motion is limited by means of the central pin 48 connecting the two panels 38 of the shelf.

The two other diametrically opposed bolts 39 are linked as shown at 51 to a freemember 52 resembling in form that of the lever 43 and also presenting an operating end 54: projecting outwardly from the shelf. The two members 43 and 52 are provided with catches 56 arranged for operative engagement with one another in the manner, .illuss tratcd in Figure 6, for retracting all the bolts when the two operating ends of the leveryettland the member 52 are pressed together, one edge 57 of the member 52 riding during this operation on a spur 58 extending toward the said edge from the lever a3 near the ivot thereof. The member 52 may be freed from interlocking engagement with the lever 43 by pushing its operating end inwardly to disengage the two catches 56. Each shelf is preferably provided with guides 63 extending laterally therefrom and adapted to ride in grooves 64 in the front posts to prevent the shelves from tilting in case the stacks are irregular in form.

The manner of using my cabinet will be readily understood from the foregoing doscription. Various articles such as books 61 or packages 62 may be placed in the compartn'ient with shelves interposed between different stacks which it is desired to keep separate, the shelves resting directly on the stack disposed underneath the same. If it is desired to gain access to a certain stack as, for instance, the books 61 without disturbing the arrangement above the same, the shelf next above the stack is engaged with the side panels by pushing in the operating end of the member 52 which"disengages the said n'lember from the lever 43 and allows all the "four bolts of the shelf to be projected into panels upwardly, the bolt 18 being automatically locked by the catch 24: when an end position has been reached. The shelf is now spaced from the stack of articles underneath the sameand convenient access may be had to the latter for the purpose of either withdrawing therefromor adding thereto. After the desired change has been made, the operator steps on the lever 28 which through the bolt 27 releases theboard 18 from the catch 24: and allows the supporting structure for the side panels to drop back intoits original position. The bolts 39 within the shelf are thereafter retracted by drawing the operating ends of the lever 43 and the member (2 together and interlocking the two whereupon the shelf will automatically come to rest on top of the stack disposed below the same.

I claim:

In a cabinet of; the character described, a

compartment having shelves therein adapted to be irregularly interposed between successive stacks of articles, slidably mounted vertical panels disposed on opposite sides of the compartment, means associated with each shelf allowing the same to be secured to the sliding panel, means for simnltaneously raising the panels, whereby the shelf secured thereto is also raised, the cabinet having caps mounted on top thereof in spaced relation ada iitcd to allow the top ends of the panels to slide threinto when the latter are raised and serving as lateral sup ports forhooks placed on top of the cabinet.
